i never remember how many % is needed,

300 %
330% ?

it got a know for the first time.

in order to win on my longest game in emerald (near 39 turns !)

300%

thank you very much !

And a loss is at 33% ???

yes but u'll rarely see it before the opponent wins, only if you actions give your opponent a country (something I doubt u'll do) will u see ur balance hit 33% before the games over.
